\VILLIAM A. DUNLAP, OF PITTSBURG, PENNSYLVANIA.

HORN.

SPECIFICATION forming part of Letters Fatent No. 586,356, dated July 131897.

Application filed August 6, 1896.

To all whmn it may concern:

Be it known that I, \VILLIAM A. DUNLAP, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Horns, 850., of which the following is a specification.

The invention described herein relates to certain improvements in hornsor other reed instruments, and has for its object a construction wherebythe reed is firmly and securely held in position.

It has heretofore been customary in the manufacture of horns forcampaign or other purposes to solder the reed to its frame or holder. Ithas been found that in such constructions the rapid vibrations quicklyrupture the solder-joint and the reed falls out. This objectionablefeature is entirely avoided in my improvement, the reed being firmlyclamped in position without the use of solder or other means which areliable to injury or destruction by the vibrations of the reed.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a I part of this specification,Figure 1 is a sectional elevation of a horn having my improvementapplied thereto. Fig. 2 is a plan view of the blank for forming thereed-frame and stopper. Fig. 3 is a plan view of the completed frame andstopper. Fig. 4 shows a perspective of the several parts. Fig. 5 is aplan view of the frame, reed, and stopper secured together. Fig. 6 is aplan view of a modified form of blank. Fig. 7 is a longitudinal section,and Fig. 8 a transverse section showing a modified form of stopper.

In the practice of my invention the reed frame or holder 1 is formed bystamping or suitable means from a piece of metal, as tin. The part 1 ismade in the form of a semicylinder, having one end closed by a wall 3,preferably rounded or curved, as shown in Figs. 1, 2, 3, 4, and 7. Theedges of the part 1 are preferably formed with an outturned flange 4 forsupporting the edges of the reed 5, which may be formed of any suitablethin metal, but preferably brass. The frame or holder 1 Serial No.601,836. (No model.)

is formed with lugs 6, which are adapted to be bent over into the edgesof the reed and firmly clamp the latter upon the frame.

As shown in Figs. 1 and 7, the frame, with the reed clamped thereon, isinserted in the small end of the horn 7 and secured in position bysolder or other suitable means. As the reed and its frame close onlyabout half of the opening in the end of the horn, provision is made forclosing the other portion of the opening by means of a strip of metal 9,having an upturned end 10, which may be clamped on top of the reed bymeans of lugs or wings 6, as shown in Figs. 7 and 8.

In Figs. 1, 4:, and 5 is shown a construction where a portion of theopening in the horn is closed by a semicylindrical piece of metal 11 ofa shape similar to the frame and having one end closed by a wallpreferably curved or rounded for convenience of manufacture. Theclosing-piece or stopper 11 is provided along its edges with flanges 12,so as to permit of its being clamped upon the reed by the lugs or wings6. As shown in Figs. 2, 3, and 6, the frame 1 and stopper 11 may beformed at one operation from a single piece of metal. When formed asshown in Fig. 2, the blank is cut in the line mm, thereby forming thetwo parts ready to be secured together on opposite sides of the reed.

In the blank shown in Fig. 6 the frame and stopper are connected by aweb 13, which is adapted to form the connection between the frame andstopper. WVhen using the form of blank shown in Fig. 6, the reed isplaced on the frame, the stopper turned over into the reed, and theparts secured together by bending the lug 6 over onto the flange on thestopper.

The mouthpiece 17 is attached by solder or other suitable means to aring 18, which is soldered or otherwise secured to the horn.

It will be observed that it is characteristic of my improvement that thereed or other parts which are subjected to vibration are attached to theframe or holder in such manner that the attaching means will not bebroken or injured by vibrations.

I claim herein as my invention- 1. The combination of a semicylindricalclamps for securing said parts together, substantially as set forth.

In testimony whereof I have hereunto set my hand.

VILLIAM A. DUNLAP.
